Preferably a reinforcing member 11 is secured, in any approved manner, to the central portion of the iframe 1 and freni there it extends inwardly to a point substantially in the plane of the lower ends of the members 4 and 5. This member 11 is formed at its lower end with a threaded bore 12 for receiving the threads 13 of the shaft 6 'for preventing lateral movement of the member 11. By means of the above described arrangements, it will be noted that a strong` unitary struotureis formed between the 'frame 1, the shaft 6, and the membersl 4, 5 and 11.

As shown in Figures 4 and 5, the reinforcing member 11 present-s a slot 14 for accommodating a portion of the shaft 15 and the pinion 16` carried at the end of the shaft 15. dvanta-.gcously the member 11 may )rovide ad'acent the inion 16 a bcarin(Y l 7 t) recess 17 in which a bearing 13 is accommodated for providing a bearing for the inner end of the shaft 15. The shaft 15 has bearing in the frame member 1 by means of ballbearing or any other kind of bearing 19, and entends to a point outwardly of the nipple 2, where it presents a V-slot 20. rlhe shaft 15 is thus arranged for rotation in the frame of the device by means of end bearing 13 and central bearing 19. In order to drive the shaft 15, a flexible shaft 21 is provided which runs to a motor or to any other rotative means and which at its lower end is V-shaped as at 22 for interlocking with the V slot 2O of the shaft 15. As the flexible shaft 21 is of the usual construction, and in fact any approved type may be used, a description thereof is omitted.

This shoe polishing machine is of the hand operated type, that is of the type which is supported by the hand of the operator and by him moved about the shoe or surface to be polished. For the purpose of affording a hand grip for the operator, a handle 23 is provided which has a through bore 24 threaded at its lower end as at 25 for engaging the threads 3 of the nipple 2 and presenting at its upper end an annular groove 26. By means of this handle 23, the whole polishing machine may be held and supported by an operator and moved about any object as the operator desires.

The flexible shaft 21 has xed tothe end adjacent the V shaped end 22 a clutch sleeve 27. This sleeve 27 adjacent its upperv end, is formed with a longitudinal groove 23, and alongside of this groove extends a flexible tongue 29V secured to the clutch sleeve 27 by means of a screw or other suitable element 30. `The tongue 29 intermediate its ends is formed with an enlargement or catch 31, adapted to be housed in the annular groove 26. Vihen the clutch sleeve 27 is inserted into the handle 23 the enlargement 31 snaps into the groove 26 to lock the clutch against outward movement.

The clutch sleeve 27 together with the fiexible shaft 21 may be removed from the handle 23 by depressing the llexible tongue 29 toward the groove 28, so as to disengage the enlargement 31 from the annular groove 26, to permit the withdrawal of the sleeve from the handle 23. Thus the flexible shaft may be connected with a power means by merely inserting the clutch assemblageA in to the handle 23. It will be noted that the clutch sleeve 27 is free to rotate. wit-hin the bore 24 of the handle 23, the latter acting as a bearing for the former.

On the shaft 6 are mounted brush ele- Y ments 32 and each of which are preferably provided with bristle 35. Each ot the brush elements 32 and 33 comprise an annular bristle back 36 which is formed adjacent one edge with an annular rabbet 37 in which is tightly fitted anend piece 38 in the center of which is mounted the bearing 39, the latter rotating adjacent the ends of the shaft 6 near the side members 4 and 5. At the opposite edge of the annular bristle backs are tightly iitted gear backs 40 to which are secured bevel gears 41 meshing with the pinion 16 and in the center of said gear backs are mounted bearings 42 which bear adjacent the center of the shaft 6 at the sides of center member 11.

The gear backs 40 may conveniently be held against an inward movement by means of pins 43 which are carried by the bristle back 36.

When the bristles of the brush elements become worn out, or when another set of brushes is wished to replace those already on the device, the nuts 10 are rst unscrewed, then the side members 4 and 5 are removed by removing screws 7, and then the brush elements are slided oil' the shaft (Sand replaced with a new set, or with a type having a cloth material instead of bristles.

From Figure 2 it will be seen that it is preferred tor-have the adjacent brush elements 32 and 33 as near together as possible and for this purpose the shaft 15 adjacent the pinion 16 is slightly reduced in diameter (as at 44) sopas to reduce the distance between the two brush elements.

The gears 41 are not absolutely necessary to drive the brush elements 32 and 33 for a friction drive may Well be substituted Jfor hand supported polishing device has been. provided, the parts of which are easily changed and replacedk without the aid of machines or specialV tools.'l The whole de- 1 vice maybe removed from the ,flexible shaft 33 driven in oppositek directions asshownv by the arrows l5 in Figure 1 and as ,under-v stood from the illustration kin Figure 2 wherein itis seen that thepinion'l engages the gears 41 at diametrically opposite points driving thel saidbrush elements in opposite directions. The device inY opera-l tion is moved in various directionsv about the shoe or boot to bepolished for' subjecting all points o-f the shoev to the rubbingy action of both elements. I

yI would state inconclusion that while the illustrated exampleconstitutes Va practical embodiment ofmy invention, I do not limit myself strictly to the `mechanical details herein illustrated,` since manifestly the same,V

can beconsiderably varied without ddepart-A ing from the spirit of the invention as de Y `-fined* in the appended claims. v v Y 3 Having described my invention I claim:
